SET OBSERVATORY

LAS\SET OBSERVATORY *
LAS\SET OBSERVATORY Name Longitude Latitude Altitude
If OBSERVATORY is *, Class will guess the observatory from the telescope
name (R%HEAD%GEN%TELES). This is the default.
If an observatory name is provided with its longitude, latitude (both
sexagesimal strings) and altitude (in kilometers), Class will use those
values independently of the telescope name. This is useful in particular
for observatories unknown by Class.
